Seriously: you could look in your user's manual if you still have it or you could go to the manufacturer's website to check it out. US bands are 850 MHz and 1900 MHz; European bands are 900 MHz and 1800 MHz (900 being the most common).
What's the make/model?
It's an LG CU515. I've got the manual. Where do I find the band info?
Oh good!
